Monosodiumphosphate nah2po4

Deuteriumoxide (D₂O), N,N,N′,N′-tetramethylethylenediamine (TEMED), ammonium persulphate (APS), phosphotungstic acid hydrate (H₃[PW₁₂O₄₀]·xH₂O), glycine, disodium phosphate (Na₂HPO₄), sodiu, dodecyl sulfate (SDS), horse heart cytochrome c (Cyt c) and bromophenol blue were bought from Sigma-Aldrich. Zirconium oxychloride octahydrate and diethyl ether were purchased from ChemLab. Aqueous hydrochloric acid (37%), potassium hydrogen carbonate and ammonium cerium^IV nitrate (CAN) were obtained from Acros organics. Ethanol, sodium hydrogen carbonate, aqueous ortho-phosphoric acid (85%), diethyalaminehydrochloride and protein ladders were acquired from Thermo Fisher Scientific. MEthanol and monosodiumphosphate (NaH₂PO₄) were purchased from VWR. Potasium chloride, tris(hydroxymethyl)aminomethane (TRIS) and acrylamide:bisacrylamide (29:1) solution (30%) were procured from Applichem. [Ce(α-PW₁₁O₃₉)₂]¹⁰⁻ (CeK) was synthesized according to (Griffith et al., 2000 (link)) [Zr(α-PW₁₁O₃₉)₂]¹⁰⁻ (ZrK) was synthesized following a slightly altered procedure from (Sokolov et al., 2007 (link)).

The hydroxypropyl methylcellulose used in this study is Methocel^® E4M Premium from the Dow Chemical Company (Mw = 290,000 g·mol⁻¹). As specified by the producer, the methoxyl content is 29% and the hydroxypropyl content is 9.7%, corresponding to an average degree of substitution of 1.9 and molar substitution of 0.23. Tetrahydrofuran (THF), 1,4-Dioxane, absolute ethanol acetone, Chloroform, Dimethylformamide (DMF) were purchased from Sigma-Aldrich (Germany). Sodium hydroxide (NaOH) and monosodium phosphate (NaH₂PO₄) were purchased at VWR international (France).
